The Honda-powered AL-KO Highline 520 VS-H is an adaptable 4-in-1 variable speed petrol lawn mower with its supreme design and build quality stemming from German engineering and Austrian manufacture.

Suitable for medium to large sized lawns up to 1,800 square metres, the 520 VS-H draws its power from a legendary Honda GCVx170 four-stroke OHV engine. The machine is easy to fire up thanks to the automatic mechanical decompression system which opens up the exhaust valve on ignition, resulting in reduced resistance in the recoil starter mechanism. The engine delivers a high power output of 3.2kW making it suitable for use in damp mowing conditions.

With user comfort a major aspect in the design process of the durable 520 VS-H, the VARIOspeed feature provides total control over the mowing speed to match both the operator's pace and the mowing conditions at hand. When combined with other comfort-enhancing qualities such as the optimum design of the cockpit with all operating controls within easy reach, a soft grip handlebar and XXL smooth-running wheels, the lawn mower is easily manoeuvrable over rough ground, even on an incline.

The self-propelled AL-KO Highline 520 VS-H is equipped with a deep MAX AIRLFLOW steel deck which maximises the mower's performance in all of the four mowing modes. The choice of collecting, mulching, rear discharging or side discharging the grass clippings is available in one multi-functional machine. In collection mode, the large 70 litre EasyClick grass box is efficiently filled from back to front to maximum capacity, with a level indicator letting you know when it needs emptying.

If you are short for space in your shed or garage, AL-KO's clever service and storage position allows the mower to be stood on end so the underside of the deck can be accessed for cleaning and maintenance, and storage space is kept to a minimum.

Featuring a generous 51cm (20") cutting width and centrally adjustable, seven stage cutting height, the AL-KO 520 VS-H Highline variable speed lawn mower is a quality all-round choice backed by a five year manufacturer's warranty and comes fully assembled in the box.

A multi-purpose machine, AL-KO's prized 4-in-1 function features mowing, collecting, mulching and side discharge capabilities.

AL-KO Highline MaxAirflow technology


Extra tall, extra large – that's the basis for MaxAirflow technology. This is because the extra tall steel plate deck and extra large discharge channel increase the airflow by 42 per cent. As a result, the grass clippings are not transported at a low level into the grass catcher as in the case of most standard lawnmowers, but are instead thrown backwards in a high arc and remain at the back. This means the grass catcher is effectively filled from the back, without the discharge channel becoming blocked. Another bonus: The removable service flap for convenient mower maintenance.

Full Catcher, Fewer Interruptions

MaxAirflow technology means that the lawn clippings are thrown to the back of the grass catcher, as a result of which it is filled to the top and does not have to be emptied so often.

No Green Fingers

MaxAirflow technology means that it is even possible to mow long, damp grass without leaving clumps behind on the ground or blocking the discharge channel. This means your hands stay cleaner.

AL-KO Service Position

An innovative AL-KO concept, this mower features a unique Service Position which enables the mower to stand on end when the fuel tank is empty.  This allows easy cleaning and maintenance of the underside of the mower deck.

I bought this to replace a 7 year old AL-KO that had done sterling service and I wanted nothing other than an AL-KO to replace it. The new model has a more powerful Honda engine (the old one had a B&S engine) and the difference is remarkable. Mowing is now done at a fast pace rather than at a plod. I am delighted.
